The function curl_easy_unescape() decodes URL encoded strings to raw binary data. URL encoded octets are represented with \%HH combinations where HH is a two-digit hexadecimal number. The decoded string is written to an allocated memory area that the function returns to the caller. The updated packages have been patched to correct this issue.
